Spanish authorities continue their investigation into the car-ramming terrorist attack that killed 14 people in Barcelona on Thursday and two related events, a gas explosion in a house in Alcanar and a car attack in Cambrils, as the nation's prime minister characterized the attack, claimed by ISIS, as "jihadist terrorism."

Based on the complexity of the plot and how quickly ISIS claimed responsibility for the attack, authorities believe that at least eight individuals may have been involved in a cell acting at the behest of the terrorist organization, The Jerusalem Postreported Friday.

Catalan government official, Joaquim Forn, told local radio that the cell likely abandoned its original plan of using a butane gas canister after encountering difficulties, and instead carried out several low-tech attacks.

It is unclear if security forces are still looking for the driver of the van in Barcelona, who escaped on foot, or if he is among the five attackers killed in a shoot-out with police on Thursday night in Cambrils, where authorities thwarted a separate attack. As of Friday morning, three people have been arrested in connection with the events.

Spanish Prime Minister Mariano Rajoy confirmed that the van attack in Barcelona was "jihadist terrorism" which he said requires a global response. "Today the fight against terrorism is the principal priority for free and open societies like ours. It is a global threat and the response has to be global," Rajoy said at a news conference in Barcelona.

U.S. to Deport Palestinian Terrorist Who Lied on Citizenship Application

A Palestinian terrorist who was convicted in a 1969 bombing that left two Hebrew University students dead was stripped of her citizenship at a court hearing Thursday and will be deported.

In April, Rasmeah Odeh admitted to lying about her past terrorist activity on her citizenship application as part of an earlier plea deal.

At the hearing on Thursday, the judge had to interrupt Odeh three times as she railed against the United States and Israel and denied that she is a terrorist.

"This is not a political forum for you to fan the flames of Israeli-Palestinian disputes. … It’s about the application you filled out,” U.S. District Judge Gershwin Drain told Odeh. He also threatened to jail her for contempt of court.

By terms of the plea deal, Odeh was stripped of her citizenship and will be deported to Jordan.

Odeh was convicted by an Israeli court in 1970 for bombing a Jerusalem supermarket on behalf of the Popular Front for the Liberation of Palestine in 1969, killing university students Edward Joffe and Leon Kanner and injuring nine other people.

“Had Odeh revealed the truth about her criminal history, as she was required to by law,” the Department of Justice said in a statement, “she never would have been granted an immigrant visa, admitted to the United States, allowed to live here for the last 22 years, or granted United States citizenship.”

When threatening that Iran could back out of the 2015 nuclear deal "within hours" if the United States imposed more sanctions on Iran, Iranian President Hassan Rouhani added that if his country restarted its nuclear program, it would be "far more advanced," than it had been before the nuclear negotiations began in 2013.

The New York Timesasserted that the threat of a more advanced nuclear program meant that Iran "could start enriching uranium up to the level of 20 percent, a step toward building a nuclear weapon."

But was it a threat? Or was it a careless admission that even now Iran is engaged in clandestine nuclear weapons research in violation of the nuclear deal?

One of the weaknesses of the nuclear deal is that it didn't force Iran to reveal the full extent of its past nuclear research.

In December 2015, a month and a half before Implementation Day, the International Atomic Energy Agency (IAEA) released a report that found that Iran had been doing nuclear weapons research until at least 2009. The IAEA, which is the nuclear watchdog of the United Nations and is in charge of monitoring Iran's compliance with the nuclear deal, couldn't say for certain whether Iran had stopped seeking nuclear weapons because Iran withheld information.

Israel will be the fifth country to host the final rounds of the world’s biggest student-run cybersecurity competition, Cyber Security Awareness Week (CSAW), on November 16 and 17 at Ben-Gurion University of the Negev in Beersheva.

CSAW was founded 14 years ago by the New York University Tandon School of Engineering and last year its final round was expanded beyond its original Brooklyn (N.Y.) location to the Middle East, North Africa and India.

This year’s CSAW signature hacking competition, Capture the Flag, will be held in Brooklyn, Abu Dhabi, France, India and Israel. This cornerstone challenge attracts upwards of 10,000 remote players each year.

Students from high school through graduate school may register on September 5 and 6 for the preliminary rounds of CSAW Israel, organized by BGU’s Department of Software and Information Systems Engineering and the IBM Cyber Security Center of Excellence, which is based at the university.

The preliminary competitions will challenge contestants’ knowledge of virtually every aspect of information security, from hardware and software penetration testing and protection to digital forensics and government policy.

At the regional CSAW campuses, students will network with top professionals who serve as judges, hear experts address emerging issues, meet recruiters eager to fill what is expected to be a shortfall of 1.5 million cyber security professionals by 2020, and face tough competition from teams from other schools. Winners of the final rounds can walk away with cash prizes, scholarships and more.
